Abstract
Background: Despite their large size, striking colouration and genital extravagance, the taxonomy of the European giant keelback slugs of the genus Limax is still poorly understood. Preliminary morphological and molecular data suggest that many unnamed or unrecognised species exist, especially in the Alps, the Mediterranean and the Balkans.

New information: We organised a citizen science expedition to Durmitor National Park in Montenegro and discovered a new species, genetically distinct, but morphologically similar to the sympatric L. cinereoniger Wolf 1803 and describe it as Limax pseudocinereoniger.

Keywords: malacology, Limacidae, slugs, taxonomy, The Balkans, genitalia

Abstract
A new species of fern, Pteris pseudoamoena (Pteridaceae), was identified and characterized. It is currently found in Guangxi Province, China, and Vietnam. Pteris pseudoamoena shares similar morphological characters with P. amoena and P. mcclurei, but can be distinguished by spores with echinate-tuberculate and auriculate ornamentation, straw-colored stipes, rachises and costae, and mostly free, occasionally interlinked veins. In addition, molecular evidence indicated that the new species is sister to a clade consisting of P. amoena, P. nakasimae and P. mcclurei.

Etymology. This species is named in honor of Ricardo Callejas. Ricardo has worked on Piper taxonomy for more than three decades. Not only is he immensely knowledgeable about species in the Neotropics (mostly) and Asia (some), but he has been incredibly instrumental in empowering young botanists, like us, to study Piper in an integrative manner. Christiane Ehringhaus called him the “Pope of Piper” (Ehringhaus, 1997); we prefer the “Father of Piper” because of his knowledge and warm welcome to anyone dedicating time to study these captivating plants.

[Fungi • 2022] Retiperidiolia gen. nov. (Agaricales: Nidulariaceae)Hidden in the Tropics: A New Genus of Bird’s Nest Fungi (Nidulariaceae), and A Systematic Study of the Genus Mycocalia


  Retiperidiolia reticulata (Petch) Kraisit., Choeyklin, Boonprat. & M.E. Sm.

in Kraisitudomsook, Choeyklin, Boonpratuang, ... et Smith, 2022. 

Abstract
Nidulariaceae (bird’s nest fungi) are an understudied group of fungi, and species of Mycocalia J.T. Palmer are the least known taxa in the family. Mycocalia was previously shown to be polyphyletic, but no further research has been conducted to revise the taxonomy of the genus. Here we conduct a phylogenetic study of Mycocalia species using five loci (ITS, LSU, SSU, TEF1, and RPB2) and morphologically examined Mycocalia collections available in herbaria. Our results indicate that two tropical Mycocalia species, M. aquaphila and M. reticulata, are distantly related to M. denudata, the type species of this genus. Accordingly, we propose the new genus Retiperidiolia to accommodate this phylogenetically and morphologically unique bird’s nest fungus lineage, with R. reticulata as the type species. Retiperidiolia reticulata was originally described from Sri Lanka by Petch in 1919. Because the type specimen is in poor condition and no molecular data can be obtained, we designated an epitype based on a recent collection from Thailand. Species of Retiperidiolia closely resemble Mycocalia species except that the peridiole cortex in Retiperidiolia species has a reticulated pattern and members of this lineage are thus far known only from tropical or subtropical habitats. In addition to phylogenetic and morphological characterization, we revised the taxonomy and provided a revised key to accepted species of Mycocalia and Retiperidiolia.

Retiperidiolia: เห็ดกลุ่มรังนก (Bird's Nest Fungi) สกุลใหม่ของโลก
นอกจากแปลกตาแล้วยังพบได้ยากมากที่สุด เนื่องจากขนาดเล็กมาก เพียง 5-10 มม. เท่านั้น ในปัจจุบันมีการค้นพบเฉพาะเขตร้อน โดยครั้งแรกพบที่ประเทศศรีลังกา ปี 1919 ครั้งที่สองพบที่ รัฐฮาวาย สหรัฐอเมริกา และค้นพบอีกครั้งในประเทศไทยในปี 2006 โดยนักวิจัยธนาคารทรัพยากรชีวภาพแห่งชาติ ดร.รัตเขตร์ เชยกลิ่น งานวิจัยนี้เป็นความร่วมมือระหว่าง ธนาคารทรัพยากรชีวภาพแห่งชาติ และ University of Florida โดยมี ดร.ณัฐพล ไกรสิทธิ์อุดมสุข เป็นผู้วิจัยต่อยอด

เอกลักษณ์หลักที่พบจนนำไปสู่การตั้งสกุลใหม่ เป็นผลจากงานวิจัยด้านสัณฐานวิทยา ควบคู่กับอณูชีวโมเลกุล พบว่า ตัวอย่างทั้งสี่มีเอกลักษณ์ที่ชัดเจน บริเวณชั้นเนื้อเยื่อผนังด้านใน หรือ peridiole cortex ที่เป็นโครงสร้างแบบร่างแห และมีผนังเซลล์หนา รวมถึง พบเซลล์สร้างสปอร์มีสองแบบคือ ทั้งที่เป็น 2 และ 4 สปอร์ 
 จึงเป็นที่มาของการตั้งชื่อสกุลใหม่ว่า Retiperidiolia แปลว่า ผนังเนื้อเยื่อด้านใน (peridiole) มีลักษณะเป็นร่างแห (reticula) 

ตัวอย่างจากประเทศไทย ค้นพบที่ อุทยานแห่งชาติทะเลบัน ถึงสองตัวอย่างซึ่งคิดเป็นร้อยละ50 ของที่พบทั่วโลก จะเห็นว่าการค้นพบนั้นเป็นระยะเวลายาวนานและการนำมาวิเคราะห์ใหม่กับตัวอย่างที่พบทั่วโลกทำให้เปิดเผยข้อมูลใหม่ๆ ขึ้นมาอีก ซึ่งผลจากการวิเคราะห์สายสัมพันธ์ทางวิวัฒนาการ (Phylogeny) สนับสนุนข้อมูลด้านสัณฐานวิทยาว่ามีวิวัฒนาการที่แยกออกมาจากสกุล Mycocaria และถ้าท่านพบสองสกุลนี้จุดที่แตกต่างกันอย่างเห็นได้ชัดเจนคือบริเวณโครงสร้างผนังชั้นใน peridiole นั่นเอง

[Diplopoda • 2022] Glyphiulus sinuatoprocessus, G. scutatus, G. xiniudong, etc. • Revision of the javanicus Species Group of the Millipede Genus Glyphiulus Gervais, 1847 (Spirostreptida: Cambalopsidae), with Descriptions of Five New Species from China

G. xiniudong Zhao & Liu, sp. nov. from Cave Xiniu Dong 

in Zhao, Guo, Golovatch & Liu, 2022. 

Abstract
The javanicus-group of Glyphiulus is re-assessed and its Chinese component species are presently divided between the following two newly-circumscribed species groups, i.e. the formosus- and the sinensis-group. The two can be differentiated, based on the diagnostic characters of the first pair of legs in the male. In addition, metatergal crests being complete and the carinotaxy formula on the collum being I–III+P+M are only characteristic of the formosus-group. A molecular phylogeny of the genus, based on DNA sequencing of four gene fragments of four genes, allows for Glyphiulus to be recovered as a monophyletic group, the phylogenetic relationship being ((Clade A, Clade B), Clade C). Molecular evidence is fully congruent with the morphological one. In addition, based on barcoding data, interspecific p-distances between Glyphiulus species amount to 11.2–24.9%, vs. 0–8.2% for intraspecific p-distances. Five new species of Glyphiulus, all cavernicolous, are described from China: G. sinuatoprocessus Zhao & Liu, sp. nov., G. conuliformis Zhao & Liu, sp. nov. (both from Guangdong Province), G. xiniudong Zhao & Liu, sp. nov., G. scutatus Zhao & Liu, sp. nov. and G. portaliformis Zhao & Liu, sp. nov. (all three from Guangxi Zhuang Autonomous Region). The known Chinese species of the formosus-group appear to mainly be confined to the South China region.

[Botany • 2022] Mitracarpus semirianus (Rubiaceae: Spermacoceae) • An overlooked New Species from the “campo rupestre” of Bahia, northeastern Brazil


Mitracarpus semirianus J.A.M.Carmo & Scatigna, 

in Carmo, Scatigna, Shimizu & Simões, 2022.

Abstract
Background and aims – Mitracarpus semirianus, an overlooked new species from the “campo rupestre” of the Chapada Diamantina, in the state of Bahia, northeastern Brazil, is here described and illustrated. Specimens of the new species have been previously identified as M. frigidus or M. lhotzkyanus, with which its distinction is discussed. We also provide an updated description of the latter, with notes on its type specimens. In addition, we comment on the distribution, habitat, and preliminary conservation status of both M. semirianus and M. lhotzkyanus. We also provide an updated identification key to the species of Mitracarpus occurring in Brazil.
Material and methods – This study was based on fieldwork collections and observations and analysis of specimens deposited in herbaria. Preliminary conservation status assessments follow the IUCN Red List criteria.
Key results – Mitracarpus semirianus differs from M. frigidus and M. lhotzkyanus by its glabrous stems, winged at each angle, wing margin hirsute, glabrous leaf blades, and the oblongoid and slightly compressed seeds, with a smooth longitudinal groove dorsally and an inverted “Y”-shaped groove ventrally. The new species is assessed as Endangered according to the IUCN criteria. Furthermore, it is more likely that Riedel, not Lhotzky, collected the original material of the name M. lhotzkyanus. This species is glabrate, not completely glabrous, presenting a generally strigose indumentum on the stems, stipular sheaths, and leaf blades.

Mitracarpus semirianus J.A.M.Carmo & Scatigna, sp. nov. 

Diagnosis – Mitracarpus semirianus is similar to M. frigidus, but differs by the glabrous stems (vs puberulent to glabrous in M. frigidus), winged at each angle (vs ribbed at each angle), wing margin hirsute (vs rib margin hirsute, strigose, or glabrous); elliptic, ovate, or narrowly ovate leaf blades, glabrous (vs narrowly ovate, rarely linear leaf blades, hirsute, pubescent, strigose, or glabrous); terminal glomerules, rarely one axillary (vs terminal and axillary, rarely just terminal); oblongoid, slightly compressed seeds (vs oblongoid to globose seeds), with a smooth longitudinal groove dorsally and an inverted “Y”-shaped groove ventrally (vs cruciform depression dorsally and an “X”-shaped groove ventrally). Mitracarpus semirianus is also similar to M. lhotzkyanus, but differs by the stems winged at each angle (vs ribbed at each angle), wing margin hirsute (vs rib margin strigose to glabrous), leaf blades with strigulose and revolute margin (vs glabrous to strigose margin and slightly revolute near the base), and the oblongoid, slightly compressed seeds (vs oblongoid to ellipsoid seeds), with an inverted “Y”-shaped groove on the ventral surface (vs a rectangular groove on the ventral surface).

Etymology – The specific epithet honours Professor João Semir, who worked at the University of Campinas (Unicamp) and passed away on the 8th of November 2018. Professor Semir dedicated his life to the study of plants. His invaluable contribution to science and society comes in the form of many theses and dissertations produced by his students, as well as works on the Brazilian flora, especially regarding the Compositae and the “campo rupestre”. He played a crucial role in the formation of generations of taxonomists at Unicamp and many other institutions, including the authors of this paper.

Abstract
Nepenthes pudica, a new species from North Kalimantan, Indonesia, is described and illustrated. The species belongs to the N. hirsuta group (sensu Cheek and Jebb 1999) but exhibits some characters that are unique within the group or even within the genus. Above all, it produces underground, achlorophyllous shoots with well-developed, ventricose lower pitchers that form in soil cavities or directly in the soil. No lower pitchers are formed above ground. The main part of its prey are ants, besides other litter- and soil-inhabiting species of invertebrates. A number of infaunal species were found in both aerial and underground pitchers, mainly Diptera and nematodes. Nepenthes pudica is known only from a few neighbouring localities in the Mentarang Hulu district of North Kalimantan, where it grows on ridgetops at an elevation of 1100–1300 m. Its discovery underlines the natural richness of Borneo’s rainforest and the necessity to preserve this important ecosystem with its enormous and still undiscovered biodiversity.

 Nepenthes pudica Dančák & Majeský, sp. nov.
 
DiagnosisNepenthes pudica differs from N. hispida Beck in producing short basal underground (vs. aboveground) shoots; ± glabrous (vs. hairy) stems; petiolate (vs. sessile) climbing shoot leaves with auriculate, shortly decurrent (vs. decurrent-amplexicaul) bases; rare (vs. common) upper pitchers; red (vs. green or red blotched) lower pitchers; ± glabrous (vs. hairy) mature pitchers; ventricose (vs. ovoid-ellipsoid) lower pitchers; infundibular (vs. subcylindrical, tapering) upper half of the lower pitcher; 3–5.5 cm (vs. 1.5–3 cm) wide lower pitchers; male flowers in pairs (vs. single or rarely in pairs) and androphore c. 4 mm (vs. 1.5–2 mm) long.

  Distribution: The species is known only from a few adjoining localities in the western part of the Mentarang Hulu district of North Kalimantan, Indonesia. The exact locations have been withheld in order to prevent poaching by unscrupulous commercial collectors.

Etymology: The specific epithet pudica (bashful, shy), is a feminine adjective and alludes to the fact that lower pitchers remain concealed from direct view.

Abstract
Here, a new species of bent-toed gecko, Cyrtodactylus phukhaensis sp. nov., is described from Doi Phu Kha, Nan province, Thailand based on molecular and morphological evidence. A phylogeny based on NADH dehydrogenase subunit 2 (ND2) and its flanking tRNAs places the new species in the chauquangensis group as a sister taxon to Cyrtodactylus wayakonei. The new species can be differentiated from other members of the chauquangensis group by having a unique combination of 7 or 8 supralabials, 23–28 longitudinal rows of dorsal tubercles, 8–10 infralabials, 9 femoral pores, 7 precloacal pores, 40–47 ventral scales, and a lack of bands crossing the temporal area. In addition, results from a chromosome study of C. phukhaensis sp. nov. showed that the new species has a diploid chromosome number of 40 with a fundamental number of 46. The formula of the karyotype was as follows: 2n (40) = 2m + 4sm + 34t. Our findings suggest that further studies of Cyrtodactylus biodiversity in northern Thailand are needed.

Diagnosis Cyrtodactylus phukhaensis sp. nov. differs from all other species in the C. chauguangensis group by having a combination of 8 or 9 supralabials; 8–10 infralabials; 36–44 paravertebral tubercles; 23–28 longitudinal rows of dorsal tubercles; 40 –47 ventral scales; 7 expanded subdigital lamellae on the fourth toe, 11 or 12 unmodified subdigital lamellae on the fourth toe, and 18 or 19 total subdigital lamellae on the fourth toe; 27–34 enlarged femoral scales; 10 –12 pore-bearing femoral scales in males; 8–11 enlarged precloacal scales; 7 pore-bearing precloacal scales in males; 3 rows of enlarged postprecloacal scales; 4–7 broken to hour glass-shaped dorsal body bands; 4–8 light-colored caudal bands (n = 2); 3–8 dark colored caudal bands (n = 2); raised and strongly keeled dorsal tubercles that extend beyond the base of the tail; enlarged femoral and precloacal scales that are nearly the same size and continuous; pore-bearing femoral and precloacal scales that are not continuous; medial subcaudals 2–3 times wider than long and extending onto the lateral side of the tail; green irises; a nuchal loop lacking an anterior azygous notch and bearing a jagged posterior border; dorsal bands bearing paravertebral elements that are generally equal in width to the interspaces, bear lightened centers, and are edged with white tubercles; dark markings in the dorsal interspaces; light caudal bands in adults bearing dark-colored markings; light-colored caudal bands that do not encircle the tail, and a mature regenerated tail that is not spotted (Table 3).

Etymology
 The specific epithet, phukhaensis, is derived from the place name of Doi Phu Kha where the type series was collected.

[Herpetology • 2022] Darevskia salihae Hidden Diversity in A Narrow Valley: Description of New Endemic Palearctic Rock Lizard Darevskia (Squamata: Lacertidae) Species from Northeastern Turkey


Darevskia salihae  
Kurnaz, Şahin & Eroğlu, 2022


Darevskia is a particularly species-rich radiation of Palearctic rock lizards from the Caucasus region. Thanks to intense systematic and taxonomic research, the knowledge of species – level diversity within this genus has increased over the last quarter century. Here, we described a new species, Darevskia salihae sp. nov. from northeastern Turkey. The new taxon is differentiated from other nearby taxon by the low number of dorsal scales in the middle of the body, the shorter body length, and the absence of blue dots both on the lateral region above the forelimbs and on the margin of the ventral plates. In addition to their morphological differences, the new taxon is phylogenetically different from close groups. It is located in a separate subclade from the rudis-valentini-portschinskii subclade. This distinction is supported by both a high bootstrap value (100) and a high posterior probability value (1.00). These two subclades are separated from each other by a genetic distance of almost 4%. This separation is supported not only genetically and morphologically, but also geographically. Since the habitat of the new taxon is limited to a high mountain and a narrow valley, it does not provide an opportunity for a different Darevskia species to shelter because it creates geographical isolation. However, Darevskia parvula that live closest to the habitat of the new taxon live only at the habitat boundaries and do not enter areas where the new taxon is found. Therefore, it might be possible that while it was separated from the rudis-valentini-portschinskii group during the evolutionary transformation, it remained as a refuge and relict in a narrow area as a result of the collapse of the valleys and the partial uplift of the Kaçkar Mountains.

Darevskia salihae sp. nov. Kurnaz, Şahin and Eroğlu, 2022

Diagnosis: Darevskia salihae sp. nov. is small sized (SVL: 51.79–58.98 mm) (Fig. 4a, b). Rostral and internasal is rarely in contact. Suboculars on both sides reach the mouth, four supralabials in anterior of suboculars. The first supratemporal plates are bigger than the others on each side of the head. All individuals have 4 supraocular plates on each side of the head. The supranasal plate is separated from anterior loreal plates above nostrils in all specimens. The postnasal plate is single on each side in all specimens. Massetericum is large and present in each side of temporal region. The row of supraciliar granules for all individuals is complete. 23–25 gularia between the third inframaxillary and collars. Generally, 6 longitudinal rows of ventral plates, and 24–30 ventral series in a longitudinal row along the belly between collar and preanal; 39–43 (mean 41) smooth dorsal midbody scales. 17–19 femoral pores exist on the right side. 22–25 lamellae exist beneath the 4th toe. The dorsal body scales in the midbody are tiny and flat. Subdigital lamellae in the 4th toe is smooth. The anal plate is singular in all specimens. Tibial scales are not carinated.

Etymology: The name of the new taxon was given in honor of Saliha Şahin, who is the mother of one of the authors, Mehmet Kürşat Şahin, who passed away recently.
